Are Beveridge Speakers worth purchasing

Given their age and dated design do they sound that good compared to more modern designs?
Yeah, if you have the room and can buy them cheap. There is a certain "magic" to these speakers that is unlike anything else.
I'm not 100% sure but I think the company has been restarted by the son of the founder of these great speakers. I had a long listen to a pair (not sure of the model) years ago, to say I was impressed is an understatement. While they didn't have the deepest bass, they had a soundstage and mid-range to die for.

The question is: "Who are you going to get to service the high-voltage, direct-drive tube amps?" I don't know if they made a model with interfaces for use with conventional amplifiers, or not... This is what I'd like to know if I were considering the purchase.
All models did not have built-in tube amp. Here is a link with info. about all past designs
